It is very hard to let a project go, but some times it is necessary. However, do you have the possibility to continue it? If you have a full time job or other incomes and this is like a hobby so far, I would continue if I was you. If you do not give up, it might prosper in the future. And if not, what does it matter. You did something you loved. I never gave up on my hobby project and finally after 4 years it is getting popular. So do not give up after only a year, if you have the possibility and wish to continue. For me, earning money on it was never a requirement, only a bonus. I just wanted to create something people want to use and see them use it. That is what makes me happy. That is also the mentality that would make you win in the end.
